摘  要:目的:探讨规范服用双联抗血小板药物对经皮冠状动脉介入治疗术(PCI)后冠心病患者预后的影响。方法:选取2008—2012年在安徽医科大学第一附属医院被确诊为冠心病并行PCI的患者489例进行随访,通过COX回归方法分析规范服用双联抗血小板药物对初级终点事件(全因死亡,非致死性脑卒中及非致死性心肌梗死)及次级终点事件(Ⅳ级心功能及再血管化治疗)的影响。结果:规范服药组初级终点事件的发生率低于非规范服药组(5%;17%,P〈0.001),两组间差异有统计学意义;而次级终点事件规范用药组发生率低于非规范用药组,但两组间无统计学差异。COX回归分析发现规范服用双联抗血小板药物可减少冠心病患者初级终点事件的发生率(RR=0.315,95%CI:0.150-0.666,P=0.002),但对次级终点事件无预测价值。进一步分析显示规范服用抗血小板药物仅对卒中发生的减少有统计学意义(RR=0.085,95%CI:0.020-0.366,P=0.001),对全因死亡及非致死性心肌梗死的发生无预测价值。结论:规范服用双联抗血小板药物可减少初级终点事件,特别是卒中的发生。Objective:To evaluate the outcome of extended use of long-term dual antiplatelt therapy (DAPT) after percutaneous coronary intervention (PCI). Method:The study enrolled 489 patients who received drug-eluting stents from 2008 to 2012. Median follow-up was 1 170 days. The outcomes were assessed as cardiovascular events including primary (all-cause mortality, nonfatal myocardial infarction and nonfatal stroke) and secondary (class IV heart failure and revascularization treatment) end-point events. Multivariable COX regression assessed the association between Long-Term DAPT and cardiovascular events. Result: Patients in on DAPT group had a significant lower rate of primary end-point events compared with patients in off DAPT group (5% vs 17%, P〈0. 001). In multivariable analysis, Long-Term DAPT could reduce the occurrence rates of primary endpoint events (RR 0. 315, 95%CI: 0. 150-0. 666, P=0. 002) and the nonfatal stroke (RR=0. 085, 95% CI: 0. 020-0. 366, P= 0. 001), but no effect on the secondary end-point events. Conclusion:Long-Term DAPT is associated with a lower rate of primary end-point events and the nonfatal stroke.
